It was the fourth violent incident on Sunday and came as Samantha Power, US Ambassador to the United Nations, visited Israel and the Palestinian territories for talks with leaders from both sides.

Earlier, two 15-year-old Palestinians fired on Israeli soldiers before being killed in the occupied West Bank.

A Palestinian man trying to stab Israeli border police between Jerusalem and Bethlehem was shot dead in the attempt and a young woman who tried to knife a policeman in Hebron was shot and taken to hospital in critical condition, police said.
